(Need help ASAP) In a research experiment, the population of a colony of bacteria doubles every hour. The population, f(x), of the colony after x hours can be modeled by the function f(x)=25 ⋅ 2x. What values for the domain are reasonable in the given context?
1. all real numbers
2. all real numbers greater than 0
3. all real numbers greater than or equal to 0
4. all real numbers greater than or equal to 25
Answer:
Step-by-step explanation:
The answer is 3
The reasonable domain is all real numbers greater than or equal to 0.
What is domain?The collection of all conceivable independent values that a function or relation may take is known as its domain.
Given:
In a research experiment,
the population of a colony of bacteria doubles every hour.
Here, we can use exponential growth function.
The population, f(x), of the colony after x hours can be modeled by the function f(x)=25 ⋅ 2ˣ.
The value of x can not be negative because it represents time.
The domain of the function is all achievable values.
So, the domain is all real numbers greater than or equal to 0
Therefore, the domain is all real numbers greater than or equal to 0.

Can someone please tell me the degree measure of angles 1,2 3 and 4?
It’ll help even more if you explain.
Answer:
angle 1 is 42
angle 2 is 138
angle 3 is also 42
Step-by-step explanation:
for angle 1, I don't remember what the exact rule was but basically since they are opposite of each other they are equal
for angle 2 all you have to do is subtract 42 from 180 because line n is at an angle of 180 and line m simply splits it into two pieces
for angle 3, I dont remember what the exact rule is or hot to explain it well but it is also 42

If ∠ G is supplementary to ∠ H and the measure of ∠ G is 65 ° what is the measure of ∠ H ?
Please help
Measure of ∠H = 115°
What are supplementary angles?Two angles are called supplementary when sum of their measures is 180 degrees.
Given,
∠G is supplementary to ∠H
∠G is 65 °
∠G + ∠H = 180°
65° + ∠H = 180°
∠H = 180° - 65°
∠H = 115°
Hence, 115° is measure of ∠H .

Choose the graph of y = -3x – 1
Answer:
The line on the graph below is my answer.
The graph of function y = -3x – 1 has been drawn below.
How to plot a graph?A graph is a diagram that shows the fluctuation of one variable in relation to one or more other variables.
In order to plot the graph, we need to find out y's values corresponding to x's value
After that, we need to substitute the values of x's and y's into the coordinate geometry.
Given the line equation y = -3x – 1
At x = 0 ⇒
y = -3(0) - 1
y = -1
So,
A(0,-1) is the first point on the line.
At y = 0 ⇒
0 = -3x – 1
x = -1/3
So,
B(-1/3,0) is the second point on the line.
Hence "The graph of function y = -3x – 1 has been drawn below".
